Application filed Gctober 13, 1913. Serial No. 795fi08t To all whom it may concern:

Be it known that 1, Srennn E. Annnnson, a citizen of the United States, residing at l Des Moines, in the county of Folk and State 1 of Iowa, have invented new and useful 1mprovements in Trusses or Bridges for Hoops of Silos, of which the following is a specification.

' The present invention relates to improvements in a truss or bridge and'more particularly to a device of this character which is to be used in conjunction with the hoops of silos for supporting the same.

The invention has for its object to provide a bridge or truss of this character which will support the hoops of the silo when passing over the door-frame.

Silos of the usual construction have substantially a cylindrical contour provided with a flat portion in which the door-frame is mounted. Hoops are then placed around the silo for bracing the same and these hoops being made of stiff material, such as cables are generally reinforced at the point where they cross the door-frame and the present invention aims to provide a truss or bridge which may be readily placed across a doorframe and not interfere with the operation of the door or the removing of the ensilage from the silo and yet support the hoops at this point.

A still further object of the present invention is to provide a truss of this character which will be comparatively inexpensive in the cost of manufacture, strong, durable and efficient when in use, which may be applied to silos of various constructions, thereby rendering the same commercially desirable.

With these and other incidental objects in view, the invention consists of certain novel features of construction, the combination of parts, and the essential elements of which are set forth in the appended claim and the preferred form of embodiment of which is hereinafter specifically described with reference to the drawings which accompany an form part of the specification.

In the drawings: Figure 1 is a front elevation of a portion of the silo having the preferred form of my invention as applie thereto. Fig. 2 is a horizontal section through the same. Fig. 3 is a horizontal section through a silo embodying another form of my invention, and Fig. 4: is a detail perg ective view.

Referring now to the drawings wherein I plurality have shown a portionof a silo of the usual knock-down frameconstruction which comprises a plurality of wooden staves A being connected together by the usual tongue and groove connection to form a circular structure, a pair of vertically extending staves B which lie in a line of the chord of the circle form the usual door jambs of the doorway between which are adapted to rest a of doors G each carrying a latch member D. i

Whereas in the foregoing, I have described portions of a silo of the knock-down frame construction it is thought that further description of the same is not necessary at the present time, as the same will be readily understood by those familiar with the art.

In Figs. 1 and 2 of the drawing, T have shown one form of my improved truss, as used in "conjunction with a metal frame for silos, which comprises a vertical angle irons E which rest the staves'B forming the door jambs and a plurality of transverse channel bars F which are-connected to the staves B in the usual manner. For bracing'silos ofthis construe tion a plurality of circumferential hoops G encircle the silo and are connected by the usual adjustable lugs H. These hoops G- are usually cables and therefore are very stiff material which when passing over the flattened face of the door-frame sag at this point and prevent the hoops from being tightened up properly. The sagging of the hoops across the doorways often results in permitting the staves A of the silo to become displaced due to their warping or contracting, thereby the silo is liable to collapse. To prevent tie sagging of the hoops across the door-frame,,l have provided a bridge or truss which comprises a single piece of sheet metal 1 which is adapted to rest within the channel bars F. This bar 1 has formed therewith raised portions 2 having recesses 3 formed herein in which rest the hoops G. These recesses also provide a support for the hoops to prevent the same from becoming displaced. The extremities of the bars 1 are provided with tapered recesses 1 through which pass the hoops G which prevent the hoops from being checked at this point so that the same may be readily tightened. From the structure of the truss bar as heretofore described, it is obvious that the same may be place orient.

doorv pair 1 of against I have pro which rests upon the oer-frame, and is se The other arms of the angle eted, to the bar 5 as at8.

In, Fig, 4 of the drawina perspective View of one 0 t the angle plates 7 which are secured to the bars 5,, but it is obvious that in silos. of the concrete, construction the angle plates 7 may be secured thereto. by means, of stud within the silo, thereby eliminating the use ofthebar 5,. From, this it is obvious, that the opening 9, formed Within one arm of the angle platemay be insertedover the stud bolts carried. by the concrete silo and the opposite arIn having formed therein the V shaped notch, 10- will formthe truss for the hoops G While the forms of the invention herein shown and described are admirably adapted to. fulfil the objects, primarily stated, it is to (hngi eeof; thispatent; may-be obtained for five cents addressing the, ,Commissioner of; Patents,

frame as be- I, have shown a bolts, anehored be understood that it is not intended to confine the invention to the forms of the embodiments herein shown and desoribed, for

claim which follows.

claim z p Thecombination of a silo of circular c0nward and-each pro ection having an openrecessin the;- ape thereof the extremities of the bar terminating ad'acent the ends of the channel member, and having inclined: recesses in itserztremities in alinement with the recessesin the projections,,to receive the encircling hoop.

In, witness whereof, I hereunto subscribe my name to, this specificationiin-the presence of two, witnesses.
